CREAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 674.623, dated May 21, 1901.

Application filed January 29, 1901. Serial No. 45,219. (N0 modeL) T0 ctZZ whom it may concern.-

Be it known that 1, JOHN D. AREAS, acitizen of the United States, residing at Bluffton, in the county of Allen and State of Ohio, have invented a new and useful Cream-Separator, of which the following is a specification.

The invention relates to improvements in cream-separators.

The object of the present invention is to improve the construction of that class of creamseparators employing an inner receptacle for the milk and an outer receptacle for containing water for reducing thetemperature of the contents of the inner receptacle and to provide a simple, inexpensive, and efficient construction for uniting the inner and outer cans or receptacles and for mounting a transparent plate or pane for enabling the contents of the inner can or receptacle to be readily inspected.

The invention consists in the construction and novel combination and arrangement of partshereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is an elevation of a cream-separator constructed in accordance with this invention. Fig. 2 is avertical sectional View. Fig. 3 is a plan View, partly in section. Fig. 41s a detail view of the outer frame or plate. Fig. 5 is a similar view of the inner frame or plate.

Like numerals of reference designate corresponding parts in all the figures of the drawings. '1' W l designates an outer receptacle or can designed to contain water for reducing the temperature of the contents of an inner receptacle or can 2 for the purpose of separating the cream from the milk to enable the same to be drawn off separately. The outer can is preferably cylindrical, and the inner can is preferably elliptical to provide ample space between the cans for the reception of the water for cooling the contents of the inner receptacle. The bottom 3 of the inner receptacle is spaced from the bottom of the outer receptacle, and the inner can or receptacle is supported at the back by means of a hook 4:, secured to the inner can or receptacle at the top thereof and engaging over the top of the outer receptacle.

The inner and outer cans or receptacles are provided at the front with vertical openings 5 and 6, and an inner plate or frame 7 is soldered or otherwise secured to the outer face of the inner receptacle. This inner frame or plate, which is approximately oblong, is provided with an oblong opening 7", and it has a rectangular flange 8 surrounding the opening and spaced from the same, as clearly shown in Figs. 2 and 3 of the accompanying drawings, to provide a seat for a transparent plate or pane 9 of glass or other suitable material. The plate or pane 9, which is secured within the flange 8 by putty 10, covers the opening of the inner frame or plate and is adapted to permit the contents of the inner can to be inspected without removing the lid. (Not shown.) The opening 7 of the inner frame or plate terminates short of. the ends of the latter, which is rounded at the said ends, as clearly shown in Fig. 5, and the said inner plate or frame is provided beyond the flange 8 with a marginal recess 11, receiving an elliptical packing 10, of rubber or other suitable material, which is interposed between the inner plate or frame and the inner face of the outer can or receptacle to provide a water-tight joint, and as the inner plate or frame is soldered to the innerreceptacle or can it will be apparent that both the water and the milk are effectually prevented from leaking.

The opening 6 of the outer can or receptacle is rounded at the ends, and the edges of the metal are arranged approximately in the same plane as the inner wall of the marginal recess of the inner plate or frame to permit the projecting portion of the said inner plate or frame to extend partially through the opening of the outer can or casing in order that the elastic packing may be compressed against the inner face of the outer can or receptacle. The packing is drawn tightly against the inner face of the outer can or receptacle by means of an upper screw 13 and a faucet 14, located at the bottom of the opening of the outer pan or receptacle. An outer frame or plate 15 is arranged on the exterior ofthe outer can or receptacle and is provided with an oblong opening 16, which is located opposite the transparent pane and which is adapted to receive the outer portions of the flange 8. The outer frame or plate is provided at its inner face with end recesses 17, having rounded end walls to conform to the configuration of the recessed end portions of the inner plate or frame. The upper screw 13 ex-. tends through a smooth perforation 18 of the upper end of the exterior frame or plate and engages a threaded perforation 19 of the inner frame'or plate. The faucet is provided with an inner threaded portion 20, extending through a smooth opening 21 of the outer frame or plate and engaging a threaded opening 22 of the lower end of the inner frame or plate. The screw and the faucet will enable the inner frame or plate to be drawn tightly against the outer can or receptacle, and the elastic packing will be sufficiently compressed to secure a water-tight joint.

The bottom 3 of the inner can or receptacle is arranged approximately in the same plane as the lower end of the transparent plane, and it is sloped toward the faucet and is provided thereat with a depression 23, extending downward to the faucet and adapted to cause the contents of the inner receptacle or can to thoroughly drain. The outer receptacle is provided with a faucet 24, adapted to permit the water to be readily'drawn off.

It will be seen that the construction for connecting the inner and outer cans at the front of the separator is exceedingly simple and inexpensive, that it will permit the contents of the inner can to be readily inspected, and that the screw and the faucet 14 will enable the projecting or offset portion of the inner plate or frame to be drawn through the opening of the outer can sufficiently to effectively compress the elastic packing to secure a water-tight joint.

The cream separator is operated in the usual manner. The milk is poured into the inner can, and the outer can is supplied with water for reducing the temperature of the milk to cause the cream to collect at the top. The milk and the cream are then drawn off separately through the faucet 14. The other faucet 24: will enable the water to be readily drawn off after the operation has been completed.

The outer frame is provided at opposite sides of the longitudinal opening with projecting longitudinal flanges 25, having curved outer edges.

What I claim is- In a device of the class described, the combination of the inner and outer receptacles, the inner frame having an opening and profrom the ends of the frame, the latter being also provided with a marginal recess 11, an outer frame having an opening to receive the said flange and provided with end recesses to -receive the projecting end portions of the inner fraine,a transparent plate mounted on the inner frame within the said flange 8, an elastic packing arranged within the marginal recess 11 of the latter, and means for connecting the frames, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in he presence of two witnesses.
